POWERplus Thunderbird 4x4 Saltwater Car DIY STEM Educational Kit (10+)

The POWERplus Thunderbird 4x4 is a DIY educational construction kit designed to demonstrate how saltwater can generate energy. This STEM-based set allows users to build a four-wheel drive (4WD) vehicle powered by a magnesium-air (Mg-Air) fuel cell.

After assembly, a small amount of saltwater activates the fuel cell, producing electricity that powers the motor and moves the vehicle. The model operates without batteries and introduces basic concepts of alternative energy, mechanics, and engineering.

The kit includes construction components, a fuel cell module, electric motor, drivetrain parts, and replaceable magnesium plates. Each refill of saltwater provides approximately 15 minutes of operation. The included magnesium plates support extended usage over multiple cycles.

This product helps develop problem-solving skills, hand-eye coordination, and understanding of energy conversion. It is suitable for children aged 10 years and above. Adult supervision is recommended during assembly.
